IMPROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 214,350, dated April15, 1879; application filed October 31, 1878.

To all whom it may concern:

Be it known that I, CORNELIUS BARNHABT, of Walker Valley, in the countyof Ulster and State of New York, have invented a new and usefulImprovement in Heating -Stoves, of which the following is aspecification.

Figure l is a vertical section of a stove illustrating my invention.Fig. 2 is a horizontal section of the same, taken through the line :20m, Fig. 1. Fig. 3 is a horizontal section of the same, taken through theline 3 y, Fig. 1. Fig. 4 is a side view of the register.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved heating-stove,which shall be simple in construction, easily manipulated, and effectivein use, which shall be so constructed that it may be used for heatingother rooms than the one in which it stands, and which will allow theparts most liable to be burned out to be easily removed and replacedwith new ones.

The invention will first be described in connection with the drawings,and then pointed out in the claim.

A represents the bottom of the stove, which is provided with feet in theusual way. B is the first section, which forms the ash-chamber, andwhich is provided with a door, 12, to admit air to support combustion,and through which the ashes are removed.

The section B is made cylindrical in form. Its lower edge rests in agroove in the bottom A, and its upper edge rests in a rabbet in thelower side of the ring 0. In the upper side of the ring 0 is formed arabbet to receive the lower edge of the section D, which forms thefire-pot. The fire-pot D is formed in one piece, and is flared downwardor made larger in its lower than in its upper part, so that there may beno place for coal, cinders, and ashes to lodge upon, to check combustionand impede the distribution of heat. The upper edge of the fire-pot orsection D rests in a rabbet in the ring E, in the upper side of which isformed a rabbet to receive the lower edge of the section F.

The section F is designed to be cast in four equal parts or pieces,which are made exactly alike, so that they can all be cast from the samepattern, and each of which is provided with a door, f, through whichfuel may be put in, or a poker inserted for stirring the fire anddumping the grate. The upper edge of the section F rests in a rabbet inthe lower side of the ring G, in the upper side of which is formed arabbet to receive the lower edge of the upper section, H. The upper edgeof the section H rests in a rabbet in the lower side of the ring I, inthe upper side of which is formed a rabbet to receive the rabbeted edgeof the top J.

The various sections of the stove are fastened together by lugs andbolts in the usual way, but which are not shown in the drawings.

With a hole in the center of the top J is connected the upper end of anair-pipe, KK, which passes down through the center of the fire-chamberand ash-pit, and its lower end is connected with a hole in the center ofthe bottom A, so that cold air may enter the lower end of the said pipeK K, be heated as it passes up through it, and escape hot from its upperend.

With this construction the cold air will enter the pipe K K withoutbeing loaded with dust and fine ashes, as it is liable to be when thesaid pipe K K does not pass through the bottom A of the stove, butterminates above the said bottom.

The air-pipe K K is made in sections, so that the part K of the saidpipe that passes through the fire-chamber and is most exposed to thefire may be readily detached when burned out, and replaced with a newone without its being necessary to renew the entire pipe.

In a groove in the upper side of the top J is placed the lower edge of acylinder, L, which has a circle of openings formed through it. Thecylinder L is provided with a cylindrical damper, M, which hascorresponding openings formed through it, so that by adjusting the saiddamper M the openings in the cylinder L may be fully opened or partly orfully closed to allow all, or some, or none of the heated air to escapeinto the room in which the stove stands, as may be desired. I

The upper edge of the register-cylinder L rests in a groove in the lowerside of a cap, N, having a hole formed through it, which may be closedwith an ornamental plug, or may be connected with a pipe to conduct theheated air or a part of it into another room to warm the said room whendesired.

P is a ring, which is provided with lugs upon its outer edge to restupon the inner part of the ring 0, and to the inner edge of which arepivoted the two semicircular parts Q. The inner edges of the parts Q areconcaved to fit around the air-pipe K.

The grate is shaken by a handle, R, which is passed into a hole in thering, I through a a slot or notch in the lower part of the section B,and is dumped by means of a poker passed in through one of the doors inthe section F of the stove.
